Photoshop batch job to adjust contrast

[oliver0541]

I have a sequence of images and would like to increase the contrast in all of them.

When I open Photoshop 2020 batch processing, there a only very few options, and among them no contrast.

Any idea ?

Batch is intended to play a referenced action set and action:

Play and manage actions

Process a batch of files

As already stated you must record Photoshop action which will run during batch process. The question is whether you want to increase contrast uniformly or per image? You have Image > Auto Contrast command which should work per image basis. Otherwise use Brightness/Contrast or Curves adjustments from Image menu or from Layer > New Adjustment Layer > B/C or Curves.

What do you mean by "record an action" and then "play an action".

Please read more about actions from official page https://helpx.adobe.com/photoshop/using/creating-actions.html

In esence Photoshop actions are macros which you can use to automate boring and repeating tasks. You can store information about steps/commands from menu which you want Photoshop to perform instead of you. File which will keep that informations are called Photoshop action which you can "play" whenever you want. When playing actions Photoshop will execute steps or commands which are stored or "recorded" into action file.

For example: action file contain instruction to go in menu File and to evoke Open command which is second option in that menu. When you play action Photoshop will open Open dialogue and wait for you to select image which you want to open.

Ah. Sounds like a good idea. Is it also possible to apply the defined actions on a set of images ?
